Next: [Samba] How to use TCP IP print port in samba
From: Alberto Moreno on 11 Jun 2010 21:30
Hi I have been working all week with samba 3.4.7 in Centos 5.5
PDC(3.4.7) with LDAP backend+Centos 5.5(3.4.7) BDC with LDAP slave.

I already have 5 clients join.

1 Windows XP
1 Windows 7 UE
1 Centos 5.5 Desktop
1 Ubuntu 9.x
1 Centos 5.5

I can browse inside windows and see my clients, access some shares. I
want to create private shares inside my PDC, I use:

force group
valid users
write list

I create a group with smbldap-tools name :it, add 2 users: test1,test2.

Centos PDC and others are enable to get users+groups from LDAP:

id test1
id test1
uid=10001(test1) gid=513(Domain Users) groups=513(Domain Users),10001(it)

I can add ldap groups to directories:

total 2088
drwxrwx--- 5 root it 4096 Jun 8 19:32 it

This is my smb.conf for this share:
[sis]
path = /opt/it
available = Yes
browseable = Yes
read only = No
guest ok = No
writeable = Yes
valid users = @it
write list = @PIMPOM\it
directory mode = 0770

I have try:
valid users: @it
valid users = \it
valid users = @PIMPOM\it

the same for write list, combinations, etc and cannot make this happen.

If I handle this by user it works, example:

valid users = test1
write list = test1

I just need this small thing to work and done.
